DOMESTIC REFRIGETRAOR SYSTEM STUDY UNIT Teaching Equipment Didactic Bench

ZM6114P DOMESTIC REFRIGERATOR SYSTEM STUDY UNIT Teaching Equipment Didactic Bench

To study the Domestic Refrigerator System and determine its power consumption, COP, theoretical & actual refrigerating effects, refrigerant flow rate & effect of door opening on power consumption & also students can visualize automatic operation of unit using a thermostat and draw PH and T-S diagrams using different refrigerants:

1. a) R134a (HFC)
2. b) R152a (HFC)
3. c) R290/R600a (50% / 50% by weight) [HC] or R600a and R290

EXPERIMENTAL SETUP

210 Litter

       Refrigerator body must be same for the different refrigerants; change can be made in compressor (hermetically sealed compressor), air cooled condenser and Expansion valve (Capillary Tube) if required

       Refrigerator should be designed for same refrigeration capacity with different refrigerants

       Refrigerator should be branded

       Sensors used for pressure and temperature should be digital, branded and accurate

       Amount of electricity consumed by every part should be measurable with an instrument (i.e. energy meter)

       Temperature (Dry as well as wet bulb) and pressure of in/out air from condenser and evaporator should be measured

       Suitable filter drier

       Temperature and pressure of in/out refrigerant from every part of refrigerator should be measured

       System should be leak proof and safe especially when using R290 /R600a refrigerants

       System should be frost free
